Serrat Flashcards
Main Vessels going To and From the Heart
Aortic
- Brachiocephalic Trunk (which divides into Right Common Carotid and Right Subclavian Artery)
- Left Common Carotid
- Left Subclavian Artery
- Abdominal Aorta
- Common Iliac (which further divides into Internal and External)
Pulmonary Trunk
Pulmonary Veins
Superior and Inferior Vena Cava
The Order of Blood Flow
Right Atrium -> Tricuspid Valve -> Right Ventricle -> Pulmonary Valve -> Pulmonary Arteries -> Lungs -> Lung Capillary Beds -> Pulmonary Veins -> Left Atrium -> Mitral Valve -> Left Ventricle -> Aortic Valve -> Systemic Arteries -> Systemic Capillary Beds -> Systemic Veins -> Right Atrium
Portal System
A venous system that links two capillary beds
Hepatic Portal System
drains blood from capillaries of digestive tract to hepatic portal vein which then branches to the capillary beds of the liver; allows metabolism and detox of materials
Hypophyseal Portal System
drains blood from capillaries of hypothalamus to the capillaries of the pituitary gland; allows for the modification of hormone release
Lymphatic Trunks
large collection of lymphatic vessels
Right Lymphatic Duct
drains lymph from upper right side of the body; enters veins at Right Venous Angle (junction of internal juglar veins and right subclavian veins)
Thoracic Duct
drains lymph from the rest of the body; enters veins at Left Venous Angle (junction of internal juglar veins and left subclavian veins)
Cisterna Chyli
merger of lymphatic trunks draining the lower half of the body
Infarct
area of ischemic necrosis due to total occlusion of an artery
Stenosis
partial occlusion or narrowing of an artery associated with tissue damage
Arteriovenous Anastomoses (AV Shunts)
areas where blood passes from artery to vein (skipping capillaries); found in skin (for temperature regulation) and gut (except during digestion)
